Abstract
Background and Study Aim. The article examines the need to implement digital tools for objective monitoring and enhancing the effectiveness of swimming instruction, driven by the increasing focus on developing aquatic competence and preventing drowning across different age groups. Purpose: to analyze the application of the developed computer program "SwimTeach Express" in the formation of swimming skills and water competence of people of different ages. Materials and Methods: the study involved 120 participants aged 6–60 years, divided into four age groups: children (6–10 years), adolescents (11–16 years), adults (17–45 years), and older adults (46–60 years). Research methods: methods of theoretical level of research; empirical research methods: pedagogical observation, pedagogical experiment; methods of mathematical statistics. Results: the study demonstrated the effectiveness of the digital platform SwimTeach Express in developing swimming skills and aquatic competence among individuals aged 6–60 years. A statistically significant improvement was recorded, with the integrated score increasing from 49.8 ± 11.1 to 83.0 ± 9.8 (+66.7%; p < 0.001). The observed changes reflect the activation of sensorimotor, respiratory, and cardiovascular adaptation mechanisms, enhancing functional readiness for activity in the aquatic environment. Conclusions: The study confirmed the effectiveness of the SwimTeach Express digital platform as an innovative tool for developing swimming skills and aquatic competence among individuals aged 6–60 years. Its application provided objective monitoring, instant feedback, and personalized learning, fostering motivation and self-regulation. The integration of pedagogical modeling, biological feedback, and digital analytics forms the basis of a new evidence-based aquapedagogy, enhancing functional readiness and safety in aquatic environments across different age groups.
